Ref: Big Bang?

Question

At the moment of Big Bang everything in our Universe came into being within time and space, if so then there must be a position in the universe where it all started as the galaxies within our universe are not in the same position as they were at T+1 ie the moment after singularity

Answer 1

This is kinda cheating - but I just posted this answer to that question a minute ago:

**********************************************************************
Since the big bang *created* space (& time), there was no "direction" to point in before then, and it actually happened everywhere.

It took me the longest time to "click" on this one, but the illustration that actually got me to understand is the "blowing up a balloon":

First, imagine space as two-dimensional, instead of three dimensional. Like the entire universe is an infinitely-large piece of paper that we are "drawings" on. We can move in two dimensions, left/right and forward/backward, but not up/down (those directions don't exist for us).

Next, curve that piece of paper into a sphere. Like a spherical balloon, where we are "drawings" on the surface. We can still move in two dimensions, but if we keep going for long enough we'll return to where we started from. We cannot move Up from the surface of the balloon or Down into the centre of the balloon. In our model, Up/Down are actually going to be Forwards and Backwards in time!

Next, compress the balloon down until it is an infinitely-small dot (the "singularity" - where the Big Bang started), and then inflate it.
Everything on the surface of the balloon (in other words, everything in the universe) is now moving away from everything else on the balloon surface, because our universe is expanding. As we move forwards in time, the balloon is expanding, and everything is moving outwards from the centre.
But, there is nowhere on the balloon surface that the Big Bang started. That was the centre of the balloon, and was when *everything* was still there.

The confusing part is then making the leap that our universe is like that balloon, except that space has three dimensions, and the universe is expanding in a fourth dimension (time).

I hope this has helped, and not just confused (or patronised) you...

Answer 2

The Big Bang was an explosion—of space, not an explosion—in space.

According to modern cosmological theory, based on Einstein's General Relativity (our modern theory of gravity), the Big Bang did not occur somewhere—in space; it occupied the whole of space. Indeed, it created space.

Because space itself is intimately connected with matter in the universe, as matter was created in the Big Bang, so was space. There is no "empty space" that the universe is expanding into; there is expansion in space-time. So, before the "Big Bang'' there was no space or time. We are not expanding into something, because that something never existed.

In this sense, the universe is self-contained. It needs neither a center to expand away from nor "empty space" on the "outside" (wherever that is) to expand into. When it expands, it does not claim previously unoccupied space from its surroundings.

We can see back towards the Big Bang itself, and detect a faint background glow from the hot primordial gases of the early Universe. This Cosmic Microwave Background Radiation (CMBR) is uniform in all directions. This tells us that it is not matter which is expanding outwards from a point, but rather, it is—space itself—which expands evenly. This uniform expanson is a key assumption of the Big Bang.

In the Big Bang model the "distance" between galaxies increases, but the galaxies themselves don't move because they are gravitationally bound. .

A good way to help visualize the expanding Universe is to compare space with the surface of an expanding balloon. If the balloon is blown up then, the distances between the dots increase in the same way as the distances between the galaxies. Think of each point on the expanding balloon as being "co-moving coordinates."

There is no center of the Universe! There is no center to the expansion. It is the same everywhere. Once again, the Big Bang should not be visualized as an ordinary explosion. The entire Universe itself is expanding, and it is doing so equally at all places, as far as we can tell.

Answer 3

The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions.
In 1927, the Belgian priest Georges Lemaître was the first to propose that the universe began with the explosion of a primeval atom. His proposal came after observing the red shift in distant nebulas by astronomers to a model of the universe based on relativity. Years later, Edwin Hubble found experimental evidence to help justify Lemaître's theory. He found that distant galaxies in every direction are going away from us with speeds proportional to their distance.

The big bang was initially suggested because it explains why distant galaxies are traveling away from us at great speeds. The theory also predicts the existence of cosmic background radiation (the glow left over from the explosion itself). The Big Bang Theory received its strongest confirmation when this radiation was discovered in 1964 by Arno Penzias and Robert Wilson, who later won the Nobel Prize for this discovery.

Although the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions.

Answer 4

You're not quite understanding.

The Big Bang was the conversion and breaking up in an outwards fashion of a singularity. It turned a singularity into a mutilarity, of you will.

As this moves out the rudimentary mass of the universe was created. The building blocks.

Be it strings, quarks, electrons, protons.

These were sent out in a random yet orderly fashion and as they hot charged partical plasma started to cool bonding started to occur.

Electrons bonded with protons to form hydrgen.

More bonding occured to form helium.

Cluters of hydrogen grouped together and fused to form stars.

Stars clusetered to form Galazies.

As stars came into being radiation was release and other bonds of free hydrogen and free helium occured giving us argon, neon, nitrogen, oxygen

At this point in time science speculates that 500 million years has passed since the universe went bang.

4 billion years later our own Sun was formed.

Answer 5

Actually the theory of singularity is correct and the universe is ever expanding. To get the point of singularity to merely reverse the process. However, there are theories that suggest that it will stop expanding and/or it will expand to the point where the distances between stars and plants will be so far, no life could ever exist again. The funny thing is, the scientific community has widely agreed that the Earth lies almost directly in the middle of the universe according to scientific models that have mapped the universe.

Answer 6

Well technically at the time of the Big Bang space itself did not exist and therefore it cannot be said that it originated at a specific point.

It boggles the mind a little when all we're used to dealing with is what we know as reality.

Answer 7

There were NO galaxies at T +1. There was completely random chaos. There were no galaxies for millions and millions of years.

Answer 8

The last i heard ,the" Big Bang"was still a theory. Is that still the case or has it been proved to be correct?

Answer 9

sorry mate, new thinking lots of bangs all the time, a reversion of black holes, so, yes we are heading for another some where, you did answer your own question ,that all items viewed or observed are not moving at the same speed therefore T+1 is scrambled, logic states there can not of been one lump if so what made it blow ?

Answer 10

Is this a question? Or just a statement of what you believe? Or just to confuse those of us that are not yet fully conscious?!
